If you are doing research about this procedure, maybe because you or a family member will undergo one, this Roux-en-Y gastric bypass guide will help to answer all the questions you might have.
1. What is the Roux-en-Y gastric bypass procedure?
The Roux-en-Y gastric bypass procedure derived its name from the French doctor, Roux, who first performed it. The Y stands for the Y-shaped tube resulting from the roux limb where the small intestine is joined.
2. How does it work?
In this Roux-en-Y gastric bypass guide, it is emphasized that like all gastric bypass surgeries, the procedure creates a small stomach pouch then reattaches the pouch to the middle part of the small intestine. A bypass is designed to result in the reduction of food intake, in addition to reducing caloric absorption of the body due to the reduced food intake. This is what makes this procedure an excellent weight-loss treatment.
3. What transpires during the surgery?
The surgical procedure, according to this Roux-en-Y gastric bypass guide, involves creating a small pouch in the stomach, with a volume of approximately 15 to 30 ml, with the use of gastric band or surgical staples. The pouch is often derived from the part of the stomach that is less likely to stretch, which is usually the upper part. The stomach pouch will literally be separated from the rest of the stomach and will be reconnected directly to the middle part of the small intestine called the jejunum, thus bypassing the lower part of the stomach and the duodenum or upper part of the small intestine. The pouch and the intestine will be connected by a tube known as the roux limb or food channel.
As you will notice in this Roux-en-Y gastric bypass guide, the activity of the lower part of the stomach will continue: regular flow of gastric juices and enzymes are maintained from the stomach and duodenum down to the small intestine, called the alimentary channel. These two channels (the food channel and the alimentary channel) will actually meet at a Y-shaped junction and will then join together for the absorption of calories and nutrients to start.
4. What will become of the unabsorbed food?
The unabsorbed food that will not be digested will pass out of the small intestine right into the large intestine. The large intestine will be the site of bacterial action wherein irritants and gases are produced. This Roux-en-Y gastric bypass guide points out that this is one of the bowel risks of the procedure.
5. Can a laparoscopic procedure be done?
The procedure can be done through either laparoscopy or open surgical method.
6. How much weight loss is expected from Roux-en-Y gastric bypass surgery?
It is typical for patients to lose just about 70% of their excess weight in the first 24 months after the procedure, according to this Roux-en-Y gastric bypass guide.
7. Can I immediately go home after the surgery?
A gastric bypass patient will usually be discharged from the hospital two to four days after undergoing surgery. This Roux-en-Y gastric bypass guide assures that normal activities can be performed in about seven to ten days afterwards. All this will depend on what procedure was done, either laparoscopic or open surgery. Barring any complication, the patient will have to go back for a post-operation checkup a week after the surgery.
8. Are there food restrictions after the surgery?
This Roux-en-Y gastric bypass guide provides that the first few days will require the patient to go on a liquid diet, while gradually moving to a puree diet. There will always be the risk of dehydration, so ensuring adequate liquid intake is important. After about a month following the surgery, patients can move to a transitional diet. They can start with a combination of eating regular foods and pureed foods. Surgical patients will tend to acquire certain healthy practices, some of which are chewing the food slowly, drinking liquid in between meals and not during meals, and eating the right kind of foods.
9. What can I get from this procedure?
This Roux-en-Y gastric bypass guide states that the main reason why patients undergo this surgical procedure is to lose a huge amount of weight.
10. Are there risks involved?
Surgical procedures always involve risks. A health concern which stems from this procedure is nutritional deficiency, which is why it is important for patients to take vitamin supplements. Infections, blood clots, and staples pulling loose are just a few of the risks.
Hopefully, this Roux-en-Y gastric bypass guide has helped you in deciding whether to proceed with the procedure or not.
